Programming Your Subaru Key Fob: A Comprehensive Guide

Is your Subaru key fob malfunctioning, or did you need a replacement? For many Subaru owners, the question of programming a new key fob often arises. While newer Subaru models typically require a visit to an authorized dealership for key fob programming, owners of older Subaru vehicles might be able to program their key fobs right at home. This guide from keyfobprog.com, your trusted automotive repair experts, will walk you through the process of programming your Subaru key fob, focusing on models that allow for DIY programming.

Is Your Subaru Key Fob Programmable at Home? Identifying the Compatible Type

Before diving into the programming steps, it’s crucial to determine if your Subaru key fob is the type that can be programmed without professional tools. Generally, Subaru key fobs that are owner-programmable have a distinctive teardrop shape. If your key fob matches this description, you’re likely in luck and can proceed with the following instructions to program your Subaru key fob yourself.

Locating Your 8-Digit Subaru Key Fob Programming Code

The first step in programming your Subaru key fob is to find the unique 8-digit code associated with your device. This code is essential for syncing your key fob with your Subaru’s system. Here’s how to find it:

1. Access the Transmitter Circuit Board: Carefully open the key fob case. This will give you access to the transmitter circuit board inside.
2. Identify the 8-Digit Number: Look for one or two series of numbers on the transmitter. Each series will be 8 digits long.
3. Record the First 8-Digit Number: Write down the first 8-digit number series on a piece of paper. Keep this number handy, as you’ll need it during the programming process.
4. Reassemble the Key Fob: Carefully put the key fob case back together once you have noted the code.
5. Prepare Your Subaru: Get into the driver’s seat of your Subaru. Ensure all doors are fully closed and the vehicle is turned off.

Step-by-Step Guide to Program Your Subaru Key Fob

With your 8-digit code in hand, you are now ready to program your Subaru key fob. Follow these steps meticulously and promptly to ensure successful programming:

1. Initial Door Sequence: Open the driver’s side door and use the door button control to unlock all doors. Then, close the driver’s side door.
2. Ignition Key Insertion: Insert your key into the ignition.
3. Ignition Cycling (Ten Times): Turn the key to the “ON” position (where the electrical systems power up, but the engine does not start), and then quickly turn it back to the “OFF” position. Repeat this cycle rapidly ten times in a row.
4. Chime Confirmation (First): Upon the tenth cycle, the instrument panel should emit an audible chime.
5. Door Sequence and Chime (Second): Open and then close the driver’s side door again. You should hear a second chime, and the vehicle’s dome lights will flash as confirmation.
6. Programming Window: Once these steps are complete, you will have a 45-second window to enter the 8-digit transmitter number into the car’s computer using the door lock/unlock button. The chime will continue during this period.

Now, to input the 8-digit code:

1. Locate Lock/Unlock Buttons: Find the lock and unlock buttons on the driver’s side door panel, typically located near the window controls.
2. Enter Each Digit: For each digit in your 8-digit code, press the “lock” button the number of times indicated by the digit, followed by pressing the “unlock” button once. For example, if the first digit is ‘3’, press the lock button three times and then the unlock button once.
3. Repeat for All Digits: Repeat step 2 for each of the eight digits in your code sequence.
4. Confirmation Chime (External): After entering all eight digits, you should hear a chime from outside the vehicle, confirming the code entry.
5. Verification Sequence: Repeat steps 2 and 3 one more time to verify that the number sequence was entered correctly. If successful, you will hear the vehicle’s locking system engage with a click.
6. Final Door and Fob Test: Open and close the driver’s side door. Then, press the “lock” or “unlock” button on your newly programmed key fob.
7. Ignition Removal and Chime (Third): Remove the key from the ignition. A chime will sound again.
8. Final Door Sequence and Functionality Test: Open and close the door one last time. Within approximately five seconds, your key fob should be functional. Test all buttons on the key fob to ensure they are working correctly.

Subaru Key Fob Battery Replacement: A Quick Guide for Newer Models

For owners of newer, rectangular-shaped Subaru key fobs, programming at home might not be an option. However, you can still handle a common maintenance task yourself: replacing the key fob battery. This is often needed when your key fob’s range decreases or it becomes unresponsive. Newer Subaru key fobs, typically rectangular in shape, use a 2032 battery. Here’s how to replace it:

Steps to Replace the Battery in Newer Subaru Key Fobs

1. Remove the Metal Key: On the back of your key fob, locate and push the small silver tab. This will release and allow you to pop out the mechanical metal key.
2. Pry Open the Fob: Insert the tip of the metal key or a small flathead screwdriver into the slot revealed after removing the key. This slot is located where the metal key was housed.
3. Open the Key Fob Cover: Gently twist the key or screwdriver in the slot to carefully separate and open the key fob cover.
4. Locate the Battery: Identify the battery inside. It might be on either side of the transmitter circuit board.
5. Battery Removal and Replacement: Remove the old battery. Note the orientation (which side is facing up) before removing it. Place the new 2032 battery in the same orientation.
6. Reassemble the Key Fob: Carefully snap the key fob cover back together until it’s securely closed. Re-insert the metal key.
